[Problem] To provide a water purifier which, when used in a water system such as a pond, lake, marsh, river, sea, sewage treatment tank, grease trap, or water tank, generates micro- or nanobubbles with ease and at low cost to purify, sterilize, and clean the water. [Solution] A water purifier which purifies the water of a water system with micro- or nanobubbles while circulating the water-system water, and is characterized by comprising: a circulation pump which is equipped with a water intake port and a water discharge port that are for the water-system water and is to be disposed in the water system; a filter which covers the water intake port to prevent floating substances in the water from coming therethrough; a tubular bypass, one end of which has been connected to the water discharge port of the circulation pump and the other end of which is a water discharge part and lies inside the filter; and a microbubble generator which has been fixed to the inside or an end of the bypass or has been connected to an intermediate part of the bypass and which allows the water-system water to pass therethrough and converts the dissolved air into microbubbles through cavitation. |
